Hello, I want to rewrite the following Matlab code to Maple sum(Yp.*X(:,2)) and si2(:,1)=1/2*(Y1(:,1)-Y2(:,1)).^2; Could you help me please? Thanks Vladimir

Does anybody know how to move the legend in the ploting area? By default, the legend sits at the bottom and outside the plotting area. Thanks.

I used Maple10 to solve an ODE from my research project and got a solution with HeunC function. I did derivative of the HeunC function and got HeunCPrime function. However I found HeunCPrime is just a sign. It cannot be valued or plotted with a selection of parameters. My questions are as follows: 1. Is there any special package I need to use to value or plot HeunCPrime function? 2. Is it possible to convert HeunC into other functions which I can manipulate for derivative and plotting?

Here's something I think TPTB at Maplesoft should be aware of. In MAPLE10, when you type ?while you get an explanation of 'while' statement used in conjunction with the 'for' statement - you don't get an explanation of the 'while' loop. For that explanation you have to go to the books. Perhaps this is corrected in MAPLE11.

I was wondering if anyone might know how to print the intermediate steps when using the dsolve function in to solve a 4th order ODE. I get the result of the dsolve function, but I want to see the actual steps that maple takes to get there. Is this feasible at all, or is there another much simpler method that I'm just not finding? Thanks in advance Jimmy Navarski

Does anyone know how use the command VolumeOfRevolution so that its plot output shows an n number of disks, instead of a continuous surface? The Volume Of Revolution Tutor allows one to specify if the output plot is in the form of a continous volume or with disks, but I can't get disks to display work from a worksheet. Thanks, Phil

Dear Sir: I try to learn to use the linear algebra in maple. I try to compute the following matrices. restart; assume(a>0,b>0,c>0); with(LinearAlgebra): M:=Matrix([[a, 0],[0, b]]); K:=Matrix([[c,-c],[-c,c]]); V:=Eigenvectors(K,M); X:=V[2]; Multiply(Multiply(X^%T,M),X); I expect that the final result should be the indentity matrix. However, it does not produce what I expect. Please give me some advice to get the identity matrix. Thank you.

It should be ~ -27700/841-21375/841*I as floats with good exactness.

Is our world could be exist in the complex space? We already know that our living space are in 3-D. But if the space we live is actually in the complex one, then that means we are living in the 6-D sapce. Maybe it is hard to say what the dimension of our space really are. One thing for sure is there always some mysteries waitting to be answered. Quantum mechanics is one big mystery in the physics, I think. What is the matter wave? What make the tunneling effect? Why we have to use the probability to describe the quantum world? There must be something we do not know yet. Is there any possibility to say that we can deal the quantum problem within the complex space, not in the Hibert space? Or is there any possibility to have a better describtion to the quantum world? Yes, I think it is.

Somethings that I would love to see in maple: 1. A visual studio Intelli-Sense like funtion so plot( would show what the parameters are. 2. In M11, when you get the auto texted arrow (->), if you assign to a variable, it would be handy to note what the variable was. 3. when you edit a auto text arrow, and it contains 'to', the 'to' becomes bolded, which looks a little jarring. 4. It would be nice to be able to assign a output to a function, not just a name. Hopefully something here might be a good idea! =) keep up the great work!

Hello, I have a question about concurent version of Maple. It is needed to install Maple on server with Flexml, as a licence server. Then I install Maple on client side with the link to the licence server. My question is: When I compute something in Maple, is it computed on server site or on my local machine and the server is only like licence server? Thank you Vladimir

Anyone having issues with the printing time in Maple 10 when there are graphs? I have to print 12 graphs for a class and it took over 20 minutes. I never had this problem in any other version of Maple. Any suggestions?

Not sure where to report this. I tried emailing tech support through the web form, but it rejected my valid product code (nice). Here's the text of my message: I've just started using Maple 11 (upgrade from Maple 10) and I'm getting a really bad crash. All I'm doing at this point is experimenting and learning (new user), so the types of input I'm dealing with are along the lines of: > restart; > plot(sin(x), x=-5..5); And the like. The problem is, in some circumstances, but not others, Maple 11 will just shut down. No messages, no warning, nothing. It's just gone, and whatever I was working

I have a simple expression of the type F:= -kT*ln(Q^N); that I am trying to manipulate, but after using "expand" the resulting expression is -kT.ln(Q^N) instead of -kT.N.ln(Q) Why "expand" does not work? Is there anything else I must do in order for expand to perform the expansion?
